Summary:

Relands the two-pass optimization for the channelwise_gated_delta_rule custom op (originally #21020, D112596724), which was reverted in D113048961 because it broke OSS unittest macos / linux.

The revert was caused by the benchmark BUCK target:

runtime.python_binary(name = ..., srcs = [...], main_module = ...)

Fix: move the source into a runtime.python_library and have the runtime.python_binary reference it via deps with only main_module
